  • Durable polycarbonate housing protects connections for long-term use

StarTech Cat6 RJ45 inline coupler 5-pack

This five-pack of female-to-female RJ45 couplers joins two Cat6 patch cables to extend a network run. Each unit uses a polycarbonate housing and gold-plated phosphor-bronze contacts to maintain signal integrity with low insertion loss. The couplers are wired to the T568B pinout and support 10/100/1000BASE-T as well as 2.5GBASE-T and 5GBASE-T links. They suit installers who need multiple quick extensions without re-terminating cables.

Replaces single couplers or field terminations

Using a pre-wired coupler is faster than crimping a new plug or punching down a keystone when a cable run falls short. The five-pack covers several drops in one purchase, reducing trips to the spares bin. The jump is worth it when you have multiple temporary or permanent joins and want consistent factory termination rather than hand-crimped ends that can introduce return loss.

Handles up to 5 Gbps over Cat6 copper

The couplers pass 10 Mbps, 100 Mbps, 1 Gbps, 2.5 Gbps and 5 Gbps Ethernet signals over standard Cat6 cabling. They run out of headroom beyond 5 Gbps or when the combined cable length exceeds the channel limit for the target speed. They are not fibre adapters and do not convert between media types, so runs requiring optical links or higher-category cable need different hardware.

Questions about this item

What physical space does each RJ45 coupler need to fit into a patch panel or wall plate?

Each coupler uses a standard keystone RJ45 footprint, so it fits any panel or plate cut for a Cat6 keystone jack without extra depth.

How are the couplers installed, and which wiring step is most often missed?

Snap each coupler into the keystone opening, then punch down both cables to the T568B colour code printed on the housing; skipping the printed code causes crossed pairs.

When will the gold-plated contacts need replacement in a typical office network?

Gold-plated phosphor bronze contacts resist oxidation for years; replace a coupler only if a cable tester shows insertion loss above Cat6 limits after re-terminating both ends.
